magnetic correlations in the extended kagome ybaco 4 o 7 probed by single crystal neutron scattering
Physical Review Letters, 2009Co-Authors: Pascal Manuel, L C Chapon, P G Radaelli, H Zheng, J F MitchellAbstract:We have studied the Frustrated System YBaCo{sub 4}O{sub 7.0} generally described as an alternating stacking of kagome and triangular layers of magnetic ions on a trigonal lattice, by single-crystal neutron diffraction experiments above the Neel ordering transition. Experimental data reveal pronounced magnetic diffuse scattering, which is successfully modeled by direct Monte Carlo simulations. Long-range magnetic correlations are found along the c axis, due to the presence of corner-sharing bipyramids, creating quasi-one-dimensional order at finite temperature. In contrast, in the kagome layers (ab plane), the spin-spin correlation function, displaying a short-range 120{sup o} configuration, decays rapidly as typically found in spin liquids. YBaCo{sub 4}O{sub 7} experimentally realizes a new class of two-dimensional Frustrated Systems where the strong out-of-plane coupling does not lift the in-plane degeneracy, but instead acts as an external 'field'.

magnetic correlations in the extended kagome ybaco 4 o 7 probed by single crystal neutron scattering
Physical Review Letters, 2009Co-Authors: Pascal Manuel, L C Chapon, P G Radaelli, H Zheng, J F MitchellAbstract:We have studied the Frustrated System ${\mathrm{YBaCo}}_{4}{\mathrm{O}}_{7.0}$ generally described as an alternating stacking of kagome and triangular layers of magnetic ions on a trigonal lattice, by single-crystal neutron diffraction experiments above the N\'eel ordering transition. Experimental data reveal pronounced magnetic diffuse scattering, which is successfully modeled by direct Monte Carlo simulations. Long-range magnetic correlations are found along the $c$ axis, due to the presence of corner-sharing bipyramids, creating quasi--one-dimensional order at finite temperature. In contrast, in the kagome layers ($ab$ plane), the spin-spin correlation function, displaying a short-range 120\ifmmode^\circ\else\textdegree\fi{} configuration, decays rapidly as typically found in spin liquids. ${\mathrm{YBaCo}}_{4}{\mathrm{O}}_{7}$ experimentally realizes a new class of two-dimensional Frustrated Systems where the strong out-of-plane coupling does not lift the in-plane degeneracy, but instead acts as an external ``field.''
